Amazon has updated its Fire TV Stick, adding 4K video capabilities and platform support for all three major high dynamic range (HDR) formats.

Another significant update is in the Stick's remote, which will finally have its own power, mute and volume controls, along with Alexa Voice Remote capabilities.
The Fire TV Stick 4K will cost $49.99, $10 more than its predecessor. Those that are happy with their streaming device but want to update the remote on its own can do so for $29.99.
